说明：  对产生的各类信号如正弦波、方波、脉冲信号、三角波等的函数使用实例(Examples of using functions of various kinds of generated signals such as sine wave, square wave, pulse signal, triangular wave, etc.)

主要是建立考虑温度场与立场耦合下的直齿轮动力学模型。通过龙格库塔法求解，得出一系列的动态特性。(The dynamic model of spur gear is mainly established considering the coupling of temperature field and position. A series of dynamic characteristics are obtained by using the runge-kutta method.)

C# 程序互斥实例，只允许运行一个程序实例的演示，互相排斥不让另一个运行，若运行两次本程序，则只有一个线程，会给出提示正在运行。

说明：  K-means算法是基于划分的思想，因此算法易于理解且实现方法简单易行，但需要人工选择初始的聚类数目即算法是带参数的。类的数目确定往往非常复杂和具有不确定性，因此需要专业的知识和行业经验才能较好的确定。而且因为初始聚类中心的选择是随机的，因此会造成部分初始聚类中心相似或者处于数据边缘，造成算法的迭代次数明显增加，甚至会因为个别数据而造成聚类失败的现象。(K-means algorithm is based on the idea of partitioning, so the algorithm is easy to understand and the implementation method is simple and feasible, but it requires manual selection of the initial number of clusters, that is, the algorithm is with parameters. The number of classes is often very complex and uncertain, so professional knowledge and industry experience are needed to better determine. Moreover, because the selection of initial clustering centers is random, some initial clustering centers will be similar or at the edge of data, resulting in a significant increase in the number of iterations of the algorithm, and even the phenomenon of clustering failure due to individual data.)
